Simplify the following equation
$6a^2 - 9b^2 + 7a^2 + 2b^2 + (-3a^2) + (-4b^2)$

Given: - $6a^2 - 9b^2 + 7a^2 + 2b^2 + (-3a^2) + (-4b^2)$

To Do: Simplify the above equation

Answer:

=$- 6a^2 - 9b^2 + 7a^2 + 2b^2 + (-3a^2) + (-4b^2)$

= $- 6a^2 + 7a^2 -3a^2 - 9b^2 + 2b^2 -4b^2$

Therefore the answer is  $-2a^2 - 11b^2$
